4. Setup
4.1 Gas Reservoir Installation and Filling
The gas reservoir is located within the buttplate of the stock. It is removable for easy filling.
- Locate the buttplate at the rear of the stock. The gas reservoir is hidden inside.
- Carefully remove the buttplate to access the gas reservoir.
- Using a suitable airsoft gas (e.g., Green Gas), insert the gas nozzle into the fill valve on the reservoir.
- Hold the gas can upside down and press firmly for 5-10 seconds until the reservoir is full. Do not overfill.
- Reinsert the filled gas reservoir into the stock and secure the buttplate.

4.2 Loading BBs into Shotgun Shells
The M870 uses removable 30-round airsoft shotgun shells.
- Hold a shotgun shell with the BB loading port facing upwards.
- Use an airsoft speedloader to insert 6mm BBs into the shell. Each shell can hold approximately 30 BBs.
- Ensure BBs are loaded smoothly and do not force them.
4.3 Loading Shotgun Shells into the Shotgun
The M870 loads shells into the chamber.
- Ensure the safety is engaged.
- Pull the pump action fully rearward to open the chamber.
- Insert a loaded shotgun shell into the chamber.
- Push the pump action fully forward until it locks into place. The shotgun is now ready to fire.

5. Operating
5.1 Firing Mode Selector
The M870 features a selector for 3-round or 6-round shot firing mode. This selector is located inside the chamber.
- Pull the pump action fully rearward to expose the chamber.
- Locate the small selector switch inside the chamber.
- Toggle the switch to select either 3-round or 6-round shot mode.
- Push the pump action forward to close the chamber.

5.2 Firing Procedure
- Ensure the gas reservoir is filled and a loaded shell is in the chamber.
- Disengage the safety.
- Aim at your target using the ghost ring iron sights.
- Squeeze the trigger to fire.
- After firing, pull the pump action fully rearward to eject the spent shell and prepare for the next shot.
- Push the pump action fully forward to chamber a new shell (if multiple shells are loaded) or to prepare for reloading.
6. Maintenance
Regular maintenance is crucial for the longevity and performance of your airsoft shotgun.
- Cleaning: After each use, wipe down the exterior of the shotgun with a clean, dry cloth. Use a silicone-based lubricant on moving metal parts to prevent wear and corrosion.
- Barrel Cleaning: Use a cleaning rod with a small piece of cloth and silicone oil to clean the inner barrel. This removes BB residue and ensures consistent accuracy.
- Gas System Care: Periodically apply a small amount of silicone oil to the gas fill valve and output valve on the gas reservoir to maintain seals and prevent leaks. Store the gas reservoir with a small amount of gas inside to keep seals lubricated, but do not store the shotgun gassed up.
- Storage: Store the airsoft shotgun in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure it is unloaded and degassed before storage.
7. Troubleshooting
Here are some common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| BBs not firing or weak shots | Low gas pressure; BBs jammed; dirty barrel; empty shell. | Refill gas reservoir; clear any jams; clean inner barrel; ensure shell is loaded with BBs. |
| Gas leaking from reservoir or shotgun | Damaged O-rings/seals; improper filling. | Apply silicone oil to valves/seals; ensure proper filling technique. If leak persists, seals may need replacement. |
| Pump action is stiff or not cycling smoothly | Lack of lubrication; dirt/debris. | Clean and lubricate all moving parts of the pump action mechanism with silicone oil. |
| Shells not ejecting properly | Pump action not pulled fully rearward; ejector mechanism dirty/damaged. | Ensure full and forceful pump action; inspect and clean ejector mechanism. |
